Abstract: A downhole tool for use in a wellbore and that is attached to a perforating string that creates perforations in a portion of the wellbore. Where the downhole tool can selectively flow fluid from the perforating string to surface, or circulate flow from surface to an annular space between the tool and a wellbore wall. The tool includes pressure actuated valves that provide the flow diverting functionality. The valves are in cooperation with one another to prevent fluid from the portion of the wellbore having the perforations from flowing into the annular space. A pressure actuated selector assembly, which is made up of a piston and specially configured mandrels that are coaxially stacked, selectively moves separate mandrels in an axial direction for opening and closing the valves.

Abstract: An electro-hydraulic actuator includes a housing having an interior portion a first opening and a second opening, a transducer is arranged in the interior portion. The transducer includes a sensor operatively coupled to a signal source at the first opening. A selectively activatable valve component is arranged at the second opening. The selectively activatable valve component maintains a desired pressure in the interior portion of the housing. An actuator is operatively coupled to the transducer and operable to activate the selectively activatable valve component exposing the interior portion to a volume of fluid in response to a signal from the transducer to activate a downhole system.
